This invention relates to new `and provernentsin an airplane. i `Morespecifically, the invention relates to an airplane having a fuselagewith laterally extending wings. It is proposed to provide rotor-likelaterally extending auxiliary wings disposed beneathsaid wings andhaving their centers located useful `im- The' invention also proposesthe provision'of e means for driving said rotor-like auxiliary wings`For further .comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawing, and to the appended claims in which thevarious novel features of the invention are` more particularly setforth.

In the accompanying drawing forming a material part of this disclosure:`

Fig. 1 is a side elevational view of an` airplane constructed inaccordance with this" invention. i

Fig. 2 is a front View of Fig. 1. l Fig. 3 is a fragmentary longitudinalsectional View taken on the line `3---3 of Fig. 2. i

Fig. 4 is a View taken `on the line 4--4 of Fig. 1.

Fig. 5 is a fragmentary enlarged detailed view of a portion of Fig. 1.

The airplane, according to this invention, is used in combination withanairplane lof any design and construction having a fuselage I I and`laterally extending wings I2. Rotor-like `laterally extending auxiliarywings I4 are disposed beneath said wings I2 and have their centers ofrotation coinciding with a shaft I5 located `on thehori- `zontal axisthrough the center of gravity, L3, L4 of said airplane and substantiallyupon a vertical axis through the center of gravity TI, T2. Eachrotor-like rotary wing I4 includes a hub portion I6 supporting aplurality of arcuately arranged blades I'I disposed upon thecircumference of a 4 of said blocks 2.

3 Claims. (Cl. 244-9) justable means includes several bell` cranks I8having substantiallyvertically extending arms I9 andhorizontally-extending arms ZIBNThevertically extending arms `I9rotatively 'support the shaft I5 which extends transversely acrosslthe`airplane between the `tip portions `of the?` wings:

I2. Eachbell crank I8 is pivotally'suppo'rtediby a pintle 2| mountedori`a block 22 whichlissup- `ported `loy an adjustment screw 23. 10ejustment EachV adscrew 23 has a screw 23 is threadedly mounted atthebase arm 25 of a vframe 2E mounted on the wing" I2. These frames 2B arelocated to the sides oi theauxiliary wingsM. f V e A block 2l' isconnected tothe extremity ofeach horizontal arm` 2G by; a pintle 28.#Each block 21 is adjustably supportedby a` vertical screw` 29.

lilach vertical 1 screw i "iii` is `threadedly engaged in the horizontalarm 25 `of aframe Each-verti cal screw 29 has a head 3@ rotativelyengaging one The pins 2t engage slots `3l in the horizontal arms `2l) onsaid bell cranks I8.

The shaft I5 is connected with a transmission by which it may bedriven.` This transmission includes a gear 32 iixedon said shaft I5 anden-` gaged by an endless chain 33 engaging over a gear 34 on the shaftof a driven engine 3'5. Sev-` eral idler gears 36 maintain the tensionof the chain 33.` These idler gears 36 are mounted on pivotally mountedlevers 3l urged outwardly `by springs `38. The springs 38 `are connected-between the levers 31 and the lfuselage II` of `the i plane. Thefuselage I I is formed with side openings 4d throughwhich said shaft I5passes. The operation of the device is as follows:

i I The rotor-like auxiliary wings I4 are indirectly driven by theengine 35." The airplane may be circle. Each rotary-like auxiliary wingI4 is substantially of cylindrical form.

Adjustable means is provided for rotatively supporting said rotor-likeauxiliary Wings I4 in various positions from said axis L3, L4 and theaxis TI, T2 to the axis LI, L2 and T3, T4 as the center of gravityshifts with changes in load. This adwards of the axis TI, T2.

rebalanced by adjusting the screws 23 for moving the rotor-likeauxiliary wings verticallyup- Wa`rdsor downwards to relocatesaidrctor-like` auxiliary wings I4 in relation to theaxis L3, L4.; Asillustrated on the drawing the rotary Wngs I4 are located on an axis L3,L4 positioned above` the. axis LI, L2. `The `screws 29 may be adjusted efor pivoting the bell cranks lifor relocating the rotor-like auxiliarywings I4 forwards or rear- For example, the auxiliary wings,` I4 may berelocated on the axis T3, T4. f

The application of my improvement to airplanes will reduce the hazard ofairplanes crash- `ing while in `flight, without deforming the'` exteriorappearance of the plane by increasing the NT OFFICE t* e head `24rotatively` ,mounted withinthe block 22. Each adjustment size or span ofthe Wings, merely by the application of propellors of least head surfacepressure to the leading edges of the planes Wings. Since thesepropellors have a full revolving radius they Will improve the stabilityof the plane and its 5 ease ofY maneuverability by increasing the highdiffusion of draft within the immediate area of its Wings.

While I have illustrated and described the preferred embodiments of myinvention, it is to be 10 understood that I do not limit myself to thepreoise constructions herein disclosed and the right is reserved to allchanges and modifications coming Within the scope of the invention asdened in the appended claims.

Having thus described my invention, What I claim as new, and desire tosecure by United States Letters Patent is:
